JOHN N. HUSHER, OF MONASSEN, PENNSYLVANIA.

CONDENSER.

Application filed May 17, 1913.

To all whom it may concern:

Be it known that 1, JOHN N. HUsHnn, a citizen of the United States, and resident of Monassen, in. the county of \Vestmoreland and State of Pennsylvania, have invented a new and useful Improvement in Condensers; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to apparatus for automatically controlling the supply of water to condensers for condensing exhaust-steam from steam engines or pumps. I I

The object of my invention isto-provide apparatus suitable for a steam condenser of the surface or jet-type in which the valve in the injector pipe for admitting water to the condenser is controlled automatically so that when the engine is not running or the load is reduced the valve will be regulated to entirely cut oil the water supply or admit just sutlicient water to effect the proper condensation of the steam.

To these ends my invention comprises thenovel features hereinafter set forth and claimed.

In the accompanying drawing the figure is a vertical sectional view of my improved apparatus.

Referring to the drawing the numeral 2 designates a suitable casing mounted on a standard or support 3. A steam-pipe 1 leading from the exhaust of the engine communicates with the casing 2 for the admission of steam to said casing. An injector-pipe 5 leading from a suitable water supply enters the casing 2 at the upper end thereof and the admission of water to said casing is controlled by a suitable valve 6. The valve-stem 7 of said valve is connected to the lever 8 which is pivoted on the standard 9. A cable 10 is connected to the valve stem 7, and said cable passes u over the pulleys 11 and 12 and has the weight 13 attached thereto which normally holds the valve open.

A rod 14 is connected to the lever 8 and said rod at its upper end is connected to the lever 15. This lever 15 is fulcrumed at 16 on the standard 17. The rod 18 is connected to the lever 15 and said rod passes down through the casing 2 to the lower end thereof, where it is connected to the lever 19. This lever 19 is fulcrumed at 20 and a rod 21 is connected to said lever and extends up within the casing and at the upper end Specification of Letters Patent.

thereof where it is connected to the lever 22 which is fulcrumed at 23 in the upright 24. A rod 25 is connected to the lever 22 and said rod extends down within the casing to the lower end thereof where it is secured at a fixed point 26. These rods 18, 21 and 25 'are preferably formed of brass pipe and mav be of any suitable length according to the height of the casing.

Within the casing are suitable baflles 27', 28, which distribute the water which overflows from the trough 29 supplied from the pipe 5. At the upper end of the casing is the pipe 30 leading to the air pump by means of which the air is carried off.

When my improved apparatus is in operation and the exhaust steam from the engine is passing from the pipe 4 into the condenser, the valve 6 normally held openby the weight 13 will permit the water to pass into the condenser where it fills up the trough 29 and overflowing said trough is distributed by the baflies 27 and 28. The water descends and through its cooling action condenses the steam in the ordinary manner of jet condensers. If, however, the load on the engine is reduced the fixed rod 25 cools 0d accordingly and as said rod is held in fixed positon at its lower end the connected to the rod 14. This will act to lower the valve stem 7 and lower the valve so as to reduce the size of the opening and the amount of Water passing to the con-- denser is accordingly reduced. If the engine should be shutdown the contraction of the rod 25 "would be sufficient to completely close the valve, thereby lifting the weight 13. Just as soon, however, as exhaust steam is again admitted to the condenser the rod 25 expands and through the rods and system of levers the weight 13 is permitted to operate to open the valve 6 and once more admit a supply of water to the condenser. By the use of this weight the lifting of the valve is not dependent wholly on the expansion of the rod 25 but as said rod expands the weight 13 is permitted to act as the rod is relieved of the strain of unseating and lifting the valve.

By my invention I provide a very simple the work being done by the engine and the waste of water is reduced to a minimum. When once the parts have been properlyad-E justed the apparatus will operate without further attention;

What I claim is:

1. In an apparatus for automatically controlling the supply of water to a condenser, the combination of a suitable casing with steam and-water inlets, a rod'in said casing fixed atone end, a lever connected tothe other end of said-rod, a-rod' in said casing connected to the opposite end of saidvlever, a valve controlling the water supply, connections between said last named rod and the valve, and a weight connected to said valve, whereby said valve is normally held in open position, the rods and lever serving as a-thermostat whereby the valve is closed.

2. In apparatus for automatically controlling the supply of water to a condenser, the combination of a casing having steam and Water'inl'ets, a-rod' within said casing fixed 25 at one end, a lever connected to the other I end'of said rod, a rod connected to the opposite end of said lever, a lever connected to theopposite end of said last named'rod, aroda-connected-to'the opposite end of said 30 last named lever, .a lever connected to the opposite end of said last-namedrod', a valve controlling the water" supply, connections between said. last. named lever and said valve, and .a weight connected to said valve, 3F whereby said valveis normally held in open position, the rods and lever 'servin as a thermostat whereby the valve is closed. a

In testimony whereof, I the said JOHN H. HUSHER, have hereunto set my hand. I JOHN- N'. HUSHER.
